UNITED STATES JOHN SISOLAK, OF CHICAGO, ILLINOIS.

WRENCH.

Application filed November 17, 1824.

To all whom it may concern.-

Be it known, that 1, JOHN SIsOLAK, a citizen of the Republic of Austria, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in renches, of which the following is a specification.

This invention relates to new and useful improvements in wrenches and more particularly to a universal wrench.

The main object of my invention is the provision of a wrench carrying movable heads having a plurality of various size sockets therein whereby the wrench may be quickly adapted for use on nuts or bolt heads of various sizes.

Another object of my invention is the provision of a wrench having movable heads provided with various size sockets or receiving openings whereby the heads may be readily positioned for operating upon nuts or bolt heads of various sizes and wherein the wrench may be disposed at dif ferent angles and, at the same time, readily grasp the nut or bolt head to be operated upon. I

A further object of my invention is the provision of a wrench including a shank or handle portion having sockets at each end thereof mounted for rotative movement with respect to the handle and provided with various sized sockets for operating upon difforent sized nuts and whereby the various sockets through the rotation of the heads may be quickly and readily brought into position for use.

With the above and other objects in view, the invention consists in the novel features of construction, the combination and arrangement of parts hereinafter more fully set forth, pointed out in the claim and shown in the accompanying drawings, in which:

Figure 1 is a top plan view of a wrench constructed in accordance with my invention,

Fig. 2 is a side elevation,

Fig. 3 is an end elevation, and

Fig. 4 is a transverse section on the line 44 of Fig. 1.

Referring more particularly to the drawings, the numeral 1 indicates the handle or body portion of the wrench, the ends of which are enlarged as at 2, and projecting from. the enlarged portions 2 are the spaced Serial No. 750,310.

cars 3 which are bifurcated to receive the pins 4 which form an axis for the rotatable head members 5 movable between the ears 3. The head members, as illustrated in the drawings, are preferably rectangular in shape, having each face thereof flattened as shown at 6, and the faces of the heads, which are at right angles to the axes thereof, are provided with sockets 7, each face being provided with a different size socket or opening 7 all of the sockets being disposed in the same position relative to the faces, whereby the device may be readily used for operating upon nuts and bolt heads of various sizes and whereby the wrench may be used to operate on nuts which are spaced from the ends of rods, bolts or the like.

The pins 4, which form the axes for the rotatable heads 5, extend through the ears 3 and through opposed side walls of the heads, as illustrated in Figure 4, the inner ends of the pins being situated in the walls of the head so as not to produce any projections upon the interior of the head. It will be apparent from the illustration in Figure 4 that the heads 5 are hollow in cross-section so that they may not only be applied to nuts or bolt heads of various sizes, but may be engaged with rods of various sizes, providing the rod is of a size to tit and conform to the shape of the lowermost opening, when the wrench head is in a position as shown in Figure 4. It will also be noted that the handle member 1 may be disposed at various angles to the work in accordance with the particular socket of the head being used, the handle, after the head has been en aged with the work, pivoting upon the pins 4.

It will be apparent from the foregoing, that I have provided a simple and inexpensive wrench particularly adapted for use in operating upon nuts and bolts wherein a single wrench may be used for engaging va rious sizes of nuts and bolt heads, and the handle member thereof may be disposed at various angles with respect to the engaging head. It will be apparent that by the use of a wrench of this character it will be possible to engage nuts and the like where it is rather unhandy to use an ordinary type of wrench.

\Vhile I have shown and described the preferred form of my invention, it will be understood that various changes and alterawalls of said socket heads and having their inner ends upset and embedded in the walls of the socket heads, said pins being mounted for rotation in the openings in the ears, and said socket heads having each face thereof at right angles to the ears provided with an opening, the openings in the faces of said 20 socket heads being of different sizes and all disposed in the same position relative to the faces.

In testimony whereof I affix my signature.

JOHN SISOLAK.
